SAFETY-ENVELOP.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed J anuary 26, 1907. Serial No; 354,326.

To all whom it may concern:

Be it known that I, liIARETOjN N. THOMP- SON, a citizen of the UnitedStates of America, residing at Enter rise, in the county of Coffee andState of A abama, have invented new and useful Improvements inSafety-Envelops, of which the following is a specification.

This invention relates to safety envelops, and one ofthe princi )alobjects of the same is to provide an env op of simple construction whichcannot be surreptitiously opened.

Another object of the invention is to provide sealing tabs at the sidesor ed es of the envelop, designed to be scaled insir e the envelop toprevent opening without detection.

These and other objects maybe attained by means of the constructionillustrated in the accompanying drawings, in which:

Figure 1 is a face view of the addressed side of an envelo made inaccordance with my invention. l ig. 2 is a rear side view of the envelopsealed. Fig. 3 is a rear side elevation of the envelop before thesealing tabs have been inserted and secured in place. Fig. 4 is a planview of the blank from which myenvelop is made.

In carrying out my invention I cut out a paper blank, as shown in Fig.4,comprising a body portion 1 having side flaps 2 provided with adhesivematerial 3 upon one edge thereof, said flaps adapted to be bent on thelines 4 to form the envelop inclosure. Parallel slots 5 are formed inthe edges of the envelop,sul stantiallfyl in linev with the foldinli-neA A sealing ap 6 provided with a ta '7,\is' gummed, as at 8, andadapted to engage an opening 9 in the lower exterior flap 10 formlng therear side of the envelop, said flap beingummed around its outer edge asat 11, an. adapted to be' bent upon the dotted line 12. At the sides ofthe flap 10 are laterally projecting tabs 13 designed to be inserted inthe slots 5 at the opposite edges of the envelop, said tabs being gummedupon one side, as at 14, to adhere to the inner, surface of the bodyportion 1 of the envelop when sealed.

In making up the envelop-from the blank shown in Fi 4, the two sideportions 2 are bent inward y upon the dotted line t and secured togetherby the gummed edge 3. The flap 10 is, then secured upon the outersurface of the side flaps 2 by means of the ginnmed edge 11. When it isdesired to seal the envelop the tabs 13 are inserted into the slots 5after the gummcd tened, and upon s g'h't pressure these'tabs aremade toadhere to theinner surface of the body portion 1. The sealing flap 6 isthen bent upon the dotted line 15, and the tab 7 is moistened andinserted in the opening 9 to seal the envelop.

From the foregoing itwill be obvious that an envelop made in accordancewith my 1nve'n'tion cannot be opened or tampered with and without easydetection. be manufactured at slight cost, and when sealed forms a.reliable and safe envelop for ordinary use.

Having thus described the invention, what 1 claim is:

portions have been 1nois-- The envelop can The herein described safetyenvelop comprising a body portion having overlapping side flaps one ateach sidethereof, the overlapping portion of one of said flaps beingsecured to the other, said side flaps and body portion havingyslotsformed therein at two."

points longitu nally in the edges thereof on the'line of foldfof saidside flaps, a back portion provided with laterally extending tabs and acentral aperture, said back portion be ing secured ing gummedandinserted in the slots and secured to. the body portion of theenvelop, and asealing flap gummed upon both of its sides provided with atab to be passed through the aperture in the back portion'of theenvelop.

In testimony whereof, I aflix my signature in presence of two witnesses.
